Quarks, gluons and the spin of the proton
Description
Experimentally, quark helicities do not seem to contribute to the proton spin. I shall show how this result can be obtained by a direct computation in a chiral field-theoretical model of quark and gluon confinement, taking gluon-exchange effects into account. At the same time, I shall get an estimate for the gluon-helicity contribution
